CANDLE.

11o Drawing.

My invention relates'to improvements in candles and more especially tothat type of candles which burn with a colored flame.

An important object of my invention is to provide a device of the abovementioned character in which the flame is colored to correspond to theodor or perfume that the candle gives off when burning.

Heretofore it has not been possible to color the flames of ordinarycandles consisting of paraflin, ceresin, etc., but I have discoveredthat with the use of inorganic wax, such as paraflin, combined withcertain acids, such as stearic and palmitic, in .combination withcertain chemicals, a candle ma be produced that will burn with a coloredame.

I contemplate adding aromatic oils and perfume bases to the candle inthe process of manufacture in such manner that odor will be producedwithout smoke.

These candles will be colored to indicate the odor they will emit whileburning, as for example, a candle that would give a lavender odorWouldbe dyed lavender.

I also contemplate coloring the flame of the candle to indicate the odorto be emitted.

I also intend indicating the color of the flame of a candle by dyeing itthat color.

For coloring the flame I intend using paraflin mixed with stearic acidagitated with air, which when mixed with certain chemicals will producecolored flames. The several chemicals that will give the candle flamethe desired color will be mixed with the inorganic wax in the properproportions (paraftin 75% and stearic acid or they may be incorporated.in aspecialiy prepared wick woven from long staple cotton to hold thcchemicals contained in solution in whichthe wick will be immersed, andthen dried, the wick being largerthan the usual wick to permit it toabsorb enough of the solutioncontaining the flame coloring chemicals toproperly color the flame. In making the candle,the mixture of paraflin75% and stearic acid 25% is melted, and when cool, but before ithardens,is agitated with compressed air which leaves the mixture light in weightand porous, allowing it toburn rapidly.

To obtain a red candle, red aniline dye is added-to the liquid Waxstearic acid mixture i and one-half ofone per centoil of rose geraniumis also added at the same time. To obtain a red flame the wick which hasbeen sat- Application filed January 30, 1925. Serial No. 5,902.

nitrate, 15 parts potassium chlorate, 4 parts antimony sulphate, and 13parts sulphur, is placed in the center of a candle mold and the coolingm xture of paraffin and stearic acid, is then poured into the moldaround the wick and cooled rapidly. In order to improve the color of theflame, 2 of a mixture of the dry chemicals spccilied above may be addedto the paraflin and stearic acid at the time the aniline dye and therose geranium oil are mixed.

I may use, for example, to obtain a blue colored flame, a combination ofpotassium nltrate 8 parts, liquid sulphur 4 parts, and copper sulphateat parts. The speciall PIG-I pared wick will be immersed-in a so ution(10%) of equal parts nitrate oflpotash and copper sulphate. Thechemicals themselves will be mixedwith the candle base in suflicientamounts to get the proper color flame for example 2 as set out above.

To, obtain a red flame I may use strontium nitrate, 2 5 parts, potassiumchlorate, 15 parts, antimony sulphate, 4 parts and sulphur, 13 parts,saturating the wick in a solution (10%) ofequal parts strontium nitrateand potassium chlorate.

The chemicals above mixed with the candle base (paraflin andstearicacid) and used for saturating the wicks are for producing the coloredflames. The color of the candle itself will be made with aniline dye.

As, an example, a candle colored with purple aniline will containessential oil lavender, which will diffuse odor as the candle isconsumed, or a candle will be colored red with aniline and combined withessential oil rose geranium.

V These essential oils are very volatile and fragrant, being evaporatedas the candle -bnrns. The heat generated by the burning will be producedwithout smoke.

It is to .be understood however that I do not restrict myself to thesecombinations of chemicals, or colors, but may resort to various changeswithout departing from the spirit of my invention or the scope of thesubjoined claims.

Having described my invention what I claim and desireto protect byLetters Patcut. is: v

urated in a solution of 25 parts strontium 1. A candle having an'incense incorpo- 1 0 I the incense in the candle.

2. A candle of inorganic waxand a fatty acid, said candle havmg saltsincorporated therein to produce a colored flame said candle being dyedthe same color as that adapted to be imparted to the flame by the salts.

3. A candle of inorganic wax and a fatty acid, an incense incorporatedin said candle, and salts incorporated in the candle and adapted to imart a color to the flame of the candle, sai color being known by a termwhich also designates the kind of incense in the candle,

4. A candle of inorganic wax and a fatty acid, saidcandle havin anincense incorporated therein, and sa ts incorporated in said candle andadapted to impart a color to the flame ofthe candle, said color of thcflame bemg known by a term which also designates the kind ofincense inthe candle, said candle being dyed the color imparted to the flame bythe salts.

In testimony whereof I afiix m signature. Y PHILIP K. UN KE.
